To all LU/1,0m, it Netty concern.-

Be it known that I, JEREMIAH HEREIN, a citizen ot' the United States, residing at l/Varsaw, in the county of Kosciusko and State of indiana, have invented a new and useful Base for Chinmoy-Stacks, of which the following is a speci'lication.

The object ot the present invention is to provide a base ior chimn y-stacls and to have the device adj-stable to 'fit chimneys of dill'erent sizes, so as to partially close the open top thereof as well as to support a metallic stack. The device is made up oi' 'fo-r drplicate sections capable of being conveniently assembled, so as to successively' overlap and embrace the four corners of a chimney, there being iastenings for connecting the sections of the device after they have been properly adjisted to tit the chimney.

The particular advantage of the present invention resides in the tact that by having the device cast it vwill be strong and durable, and therefore ontlast several sheet-metal stacks, it being necessary to replace the stack only when the latter has become burned out or otherwise damaged.

With these and other objects in view the present invention consists in tion and arrangement of parts as will be herein att er more i'ully described, sh own in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that changes in the torni, proportion, size, and minor details may be made within thescope ot the claims without de parting from the spirit or sacrificing any of the advantages oi the invention.

ln the drawings, Figure 1 is a perspective view showing a device of the present invention 'fitted to the top of a chimney and sup porting a sheet-metal stack, the foot ot the latter being broken away, so as to disclose all of the base. Fig. 2 is an enlarged fragmentary sectional view on the line 2 2 ot Fig. 1. Fig. 3 is a cross-sectional view on the line B 3 oi Fig. 2. Fig. e is a detail perspective view or one of the duplicate sections of the device.

Lilie characters ot reference designate corresponding parts in all oi the iigures oi' the drawings.

As hereinbeiiore indicated, the present device is made up of four duplicate sections, one oi' which has been shown in detail in Fig. l ot the drawings, and is substantially L-'shaped in Vforni, including one relatively long flat member 1 and a shorter flat memthe combinaber 2, set at right angles thereto. An upright flange 3 depends from the outer edge of each member ot' the section and terminates in an outwardly iiared lower portion 4. From the inner edge of each member there j rises an inwardly-bowed or arched hood portion 5, from the inner edge of which rises an l upright flange 6, which inclines slightly inward. Upon the upper face of' the member 2 and leading inwardly a siitable distance Jfrom its outer end is an upstruclr socket 7, whichl is closed throi'ghout its top and open at its bottom with openings 8 adjacent each end thereof. A boss 9 is provided rpon the upper tace of the member 1, adjacent its l Outer end, and has a longitudinal slot 10.

In assembling the device preparatory to iitting the same to the top of a chimney, such as shown at 11 in Fig. 1 of the draw- 1 ings, the four sections are brought together and successively overlapped, so as to form a rectangular cap, with the boss 9 of each section received within the socket 7 of the adj acent section, the slot of each boss being registered with one of the openings 8 of the adjacent socket. A bolt 12 is passed downl wardly through each slot 10 and the adjacent opening 8, and a nut 13 is iitted to the lower end ci' the bolt and received within the hollow boss 9. It will here be .explained l, that the cap-sections are merely loosely conl nected prior to being iitted to the chimney,

l and after the sections have been snugly embraced upon the top of the chimney the j bolts are tightened by means of a screw# 'j driver, as the nuts 13 are held against rotation in the bosses 9 and rest upon the top of l the chimney. Additional security may be l given to the cap by vmeans of mortar or cement applied to the top of the chimney prior l to itting the cap thereto, or mortar or cement l may be placed in the annular recess formed l between the walls of the chimney and the l flared portion 4 of the vflange 3. After the cap has been tted to the chimney the metallic stack 14 is set down around the upl standing ilange 6, with its bottom resting upon the hood 5, and suitable guys (not shown) may be employed to brace the stack. Freni the foregoing description it will be j understood that the device of the present inl vention is to be cast in Jfour duplicate secl tions, which are proportioned so as to sucl cessively overlap when assembled and capable ci being adjusted, so as to fit the standard sizes oi chimneys. By having the cap IOO separate from the sheet-metal stack the latter may be replaced several times without the necessity of' replacing the cap.

Having thus described the invention, what is claimed is* l. A device of the character described comprising complementary sections each provided with a hood portion capable of being adjustably overlapped when assembled and adapted to partially close the open end of a chimney and forni a support for a chimney-stack, each section being provided at its outer edge with a depending flange and at its inner edge with an upstanding flange, and fastenings to connect the overlapped portions of the sections.

2. A device of the character described comprising` four duplicate corner-sections capable of being adjustably overlapped. when assembled and each provided with an inwardly-extending hood adapted to partially close the open end of a chimney and form a support for a chimney-stack, said. sections being provided at their outer edges with depending flanges and at their inner edges Wi th upstanding flanges, one of said sections being provided with an upstruck perforated socket and the mating section with a slotted boss adapted to engage said socket, and fastening devices extending through the perforations and slots of' the several sections.

3. A device of the character described comprising duplicate sections capable of being adjustably overlapped when assembled, each section being provided with a depending flange at its outer edge, an arched flange at its inner edge, an upstanding flange at the free edge of the arched if'tnge, and fastenings to adjustably connect the overlapped portions of the sections.

4. A device of the character described comprising adjustable overlapped sections each provided with a hood portion adopted to partiallyclose the open end of a chimney and forni a support for a chimney-stack, one section having a socket, which is open in its under side and pierced by an opening, the adjacent overlapped section having an upf standing hollow boss to fit within the socket `land provided with a slot for registration with the opening of the socket, and a fasten- I ing to extend through the slot and the openl 111g.

5. A device of the character described comprising a series of duplicate corner-sections each provided with a hood portion adapted to partially close the open end of a l chimney and form a support for a chimneystack, one member of each corner-section I having a longitudinal slot open throughout i its under side and provided with an opening l through its back, the other member of the i section having an upstanding hollow boss open throughout its under side and provided l. with a longitudinal slot, the boss of each seca tion being adapted to adjustably fit Within the socket of the adjacent overlapping sec` I tion, and fastenings to pass through the openl ings of the sockets and the slc ts of the bosses. 6. A device of the character described l comprising four 'duplicate corner-sections i each section including a substantially L- shaped body having a ,depending flange throughout its outer edge, an arched flange rising from the inner edge of the body, and I an upstanding flange at the free edge of the arched flange, one body member of each section being provided with an upstanding socket leading inwardly from one end and l' open throughout its under side with open= ings adjacent its ends, the other body memi ber having an upstanding boss open throu'g'lk y out its under side and provided with longitu'dinal slot, the bosses being adjustably re- I ceived Within the successive sockets When I the sections are assembled, bolts passing through the openings of the sockets and the i slots of the bosses, and nuts fitted to the bolts i and received within the bosses.

In testimony that I claim the foregoing as my own I have hereto afliXed my signature in the presence of two witnesses.
